v3.4.0

Highlights

• Block creation and editing now preserve arbitrary AFFiNE inline text attributes, including colors and highlights, through a lossless delta input and output path.
• Upstream HTTP response handling now enforces a 16 MiB body limit and keeps request deadlines active until each body is fully consumed.
• Empty workspace and profile updates fail before mutation, while ignored-only surface updates avoid unnecessary CRDT pushes.
• CI now validates every supported even-numbered Node.js release from 20 through 26.

What Changed

• Formatting-preserving block text
  • append_block.text and update_block.text accept either a plain string or a delta array with arbitrary inline attributes.
  • read_doc and block-editing receipts return canonical deltas alongside flattened text.
  • Empty delta content is normalized consistently when validating divider blocks.
  • String inputs and existing response fields remain compatible.
• HTTP response safety
  • GraphQL, authentication, readiness, CLI, blob-upload, and workspace-creation paths share one bounded response reader.
  • Slow or oversized response bodies fail predictably instead of bypassing the request deadline or consuming unbounded memory.
  • Diagnostic response bodies are cancelled when their content is not needed.
• Mutation handling
  • update_workspace and update_profile require at least one meaningful field.
  • Surface and edgeless updates that contain only ignored elements do not send unchanged Yjs state.
  • AFFiNE document and workspace identifiers use the shared cryptographically secure generator.
• Runtime validation
  • CI covers Node.js 20, 22, 24, and 26.
  • Node.js type definitions are aligned with the minimum supported runtime.

Compatibility

• The canonical MCP surface remains at 96 tools; no tools or existing required inputs were removed.
• Plain-string block text remains supported, and delta arrays are an additive input and output path.
• Node.js 20.18.1 or newer remains required.
• Release behavior is validated against AFFiNE 0.27.4.

Validation Evidence

• Node.js 20.20.2, 22.23.2, 24.20.0, and 26.7.0: clean npm ci && npm run ci
• npm audit --audit-level=low with zero vulnerabilities
• AFFINE_REVISION=0.27.4 npm run test:comprehensive (16 focused integrations; 111/111 comprehensive checks)
• AFFINE_REVISION=0.27.4 npm run test:e2e (24 integration tests; 17 Playwright tests)
• Isolated database UI row integration coverage
• Packed-tarball install, CLI, and 96-tool discovery smoke on Node.js 20 and 26
• npm publish --dry-run --access public --ignore-scripts
• Linux/amd64 Docker build, version check, non-root UID check, and healthcheck smoke
